Consult everybody:
I realized in development board 4 g module AT commands even outside network,
And 4 g module interaction AT commands are through the
The next step is to deal with the outside network
This step I searched online to say to want to write a few feet, under PPP,
Finally is done with PPPD run the script,
I in this development board system does not support PPPD,
A running PPPD command will prompt:
Couldn 't open the/dev/PPP device: No to device the or address
PPPD: both Please load the ppp_generic kernel module.

This system also brush I

Do you have any other way without PPPD to perform?

Thank you for your attention!
